DAILY PILE CROPPER MAINTENANCE

 

In order to ensure the pile cropper continues to function correctly and safely, it is imperative that daily inspections and maintenance are conducted prior to use.

Each cropper type will be delivered with a method statement giving details of correct use.

Daily checks as follows:

  1. Ensure lifting chains/frames are correctly connected to cropper and inspection date is valid.
  2. Check hydraulic hose integrity and ensure connections are leak free.
  3. Check Kevlar hose shrouds are in good condition.
  4. Inspect the cutting face of the jaws – check that wear is not excessive, if unsure, please contact APC to discuss
  5. Re-grease moving parts using the identified grease points.
  6. Test cropper on an excavator.

Australian Pile Croppers are committed to your safety. All pile croppers are delivered with fully certified lifting equipment . A copy of the ‘life’ certificate for the chains can be obtained on request from jim@australianpilecroppers.com.au

It is your responsibility to check chain certification date is valid and notify of pending re-inspection requirement. We will then arrange re-inspection as required.

It is also your responsibility to provide a suitably certified and correctly sized `D` shackle to secure the cropper to your excavator. As a standard we will deliver the cropper to site and hydraulically connect the cropper to the machine via quick release couplings and test the unit on a sample pile to ensure its suitability. Once the hire period is complete we will remove the quick release couplers and return the machine to its original state.

    USAGE SAFETY

     

    1. Always cut piles from the top downwards and not from any other position on the pile.
    2. We recommend a saw cut (Ringbarking) be etched at finish level to prevent fractures below the required RL.
    3. Ensure your on site banksman has moved to a safe distance once cropper has been positioned over pile.
    4. Use a machine capable of carrying the cropper plus excess pile.
